400 watts is more than enough for your system (your system will not draw more than 250 watts under full stress), what people mean is that that Cooler Master PSU might not be a quality one. If you are not going to overclock, the PSU will handle the system. But better to be safe than sorry, if you can afford it, get better PSU in the future form the brands such as: Corsair (avoid CX units), XFX, SeaSonic or Antec

The problem is that CM elite power is not a good PSU here is a review of one version of it http://www.hardwaresecrets.com/article/Cooler-Master-El... this one is made by FSP and is reasonable but there is another one made by Solytech which is a lower ranking manufacturer than FSP and could be worse quality. The FSP one has part number ending in J3 the solytech one I3.

A Radeon HD 7850 needs at least 21 amps on the 12v rail and a 500 watt power supply.

If you want a solid great priced 550w SEASONIC UNIT with 45 amps on the 12v rail here you go.
